Pollution and global warming are the two most critical environmental issues at the moment. However, a good number of alternative solutions have evolved with the rise of awareness on these two issues. For instance, the emergence of wind power as a renewable energy is a very positive sign. Unlike fossil fuels, wind power energy does not pollute the environment. Therefore, it is definitely a front runner amidst all alternate energy sources.

However, you would be surprised to know that the wind power is not a very new concept. Wind mills existed from a very long time. In the olden days, wind mills were utilized for common mechanical purposes such as pumping of water; nowadays, wind mills are used for generating electricity. This is the difference between now and then. People have become a lot more environment conscious. The awareness level about environmental pollution has reached its high. But the sad thing is that though the knowledge and education is there with the people; the implementation of the acquired knowledge and awareness is missing. As a result, resources like the wind power energy are not been utilized to their fullest. And this is a shame.

However, the advancement of technology for the right purpose gives hope. Today, even the concept of wind turbines in your home does not seem like a dream. Once they get installed, you get the option of enjoying the renewable energy sources of the wind power, as long as you wish from your home. Therefore nothing is impossible, only if the intention of man is correct. So, if you consider renewable energy resources seriously, then verify with the authorities in your locality. Check with the rules in relation to installing a wind turbine, in the locality where you stay.

The utilization of wind power is not limited to the wind turbines only. Today, it is used in a great number of ways. The foldable flettner rotor in this context deserves a special mention. The flettner rotor is a high spinning metal device that is installed in the deck of the ship. The wind power energy gets converted into forward thrust with the help of this device. The rotor stays almost perpendicular towards wind direction and permits a ship to save almost twenty percent of the fuel cost. Such eco-efficiency technology is definitely a boost to the shipping industry.

There is little doubt about the benefits of wind energy. Architects, farmers, and sailors, over the years recognized its energy and utilized it in their favor. Unlike wind energy, the geothermal energy is tapped from the heat of earths crust. Here the purified steams are being utilized for driving turbines. Like the foldable flettner rotor, the geothermal turbine gets converted into a power source for the electric generators. However, the downside for this form of energy is its high cost. Otherwise, the geothermal energy is a promising renewable energy resource. Therefore, the more these two forms of energy are utilized, the better it is for mankind and the environment.
